product description
Excellent Spectral Characteristics: Operating wavelength range typically 1528-1603nm, spectral width up to 75nm, covering both C and L bands. Suitable for various applications requiring broad spectrum, such as testing device performance at different wavelengths during production.
High Spectral Flatness: Utilizes spectral flattening technology achieving flatness better than 3dB. This ensures a relatively uniform power distribution across the output spectrum, guaranteeing consistency and accuracy in measurements or applications at different wavelengths, enhancing test and application precision.
Output Power Advantage: Output power can reach 20mW or higher. Various power levels are available (e.g., 13dBm, 15dBm, 17dBm, 19dBm), providing sufficient optical power for device testing, fiber sensing, etc., meeting requirements for long-distance transmission or high optical power.
Adjustable Power: Typically features power adjustability from 10% to 100% while maintaining spectral flatness. Users can precisely adjust output power according to actual needs, adapting to different test or application conditions.
High-Precision Temperature Control: Employs a high-precision ATC system alongside specialized circuit design (ACC and APC), effectively controlling pump output to ensure laser output power stability, reducing the impact of temperature variations on performance for stable operation in diverse environments.
Optimized Optical Path Design: Based on EDFA gain, the optical path design is simple with high optical-to-optical conversion efficiency, reducing losses and potential failure points. Global optical feedback control technology ensures stability of output power and spectral shape, enhancing source reliability.
Multiple Form Factors: Available as compact modules for easy integration into other systems, or as benchtop units, meeting various user needs and installation conditions.
